Project website "Wintaro"
445 USD Project: MVP crypto-casino with the game Crash
Goal: Create a working version of a mini-casino with one game (Crash), registration via email and nickname, acceptance of cryptocurrency, Provably Fair, and a basic admin panel.
Registration:
Form with 2 fields: email, nickname
Uniqueness of the nickname, email validation
Login via email (session storage through JWT)
Email confirmation is not required for MVP
Ability for automatic login on re-entry (token storage)
Game: Crash
The user places a bet and clicks "Start"
The coefficient increases (example: 1.00x, 1.12x, 1.45x...) until a random crash
The player can "cash out" the bet before the crash (win = bet * coefficient)
If they are too late — the bet is lost
Provably Fair:
A hash of the result is shown before the game
After — seed and crash multiplier
Player's betting history
Balance and crypto:
The player sees the balance in USDT
Generation of a unique deposit address
Tracking incoming transactions to the address
Automatic balance crediting upon transaction confirmation
Withdrawal: through the admin panel or via a button with confirmation (by email or manually)
Admin panel:
User table (email, nickname, balance)
Search by email/nickname/address
View bets, deposits, and withdrawals
Button "Block player"
Ability to process withdrawals manually
Stack (preferred):
Frontend: React.js + Tailwind CSS
Backend: Node.js (Express or Nest.js)
DB: MongoDB or PostgreSQL
Wallets: Web3.js / Ethers.js or BlockCypher API (for monitoring)
Auth: JWT
Bonus:
It is preferable to use a proven algorithm for fair RNG
Ready-made UI templates can be used (for example, Tailwind UI or Figma)

Hello! I have reviewed your technical assignment — the task is very interesting and quite feasible at the MVP level. I suggest implementing the project from scratch using a modern stack, as transparently as possible, with the potential for further scaling.
🔧 What I will do:
I will implement registration via email and a unique nickname, JWT authorization with auto-login.
I will create the main mechanics of the Crash game — coefficient growth, the ability to cash out the bet, random crash.
I will integrate Provably Fair mechanics with the generation and verification of seeds and hashes.
…
User balance in USDT, with the generation of a unique deposit address (via Web3.js / Ethers.js).
Automatic balance replenishment after transaction confirmation.
A basic admin panel for tracking deposits/bets/withdrawals with the ability for manual withdrawals and player blocking.
A fully responsive frontend on React + Tailwind with the ability to use.
I will use PostgreSQL or MongoDB depending on scalability requirements.
📌 From my side:
The code will be clean, modular, and ready for development.
All basic improvements after launch will be included in the cost.
I will provide technical support for launch and hosting (if necessary).
I can offer additional features if needed (chat, player leaderboard, game history output, etc.).
I would be happy to discuss the details and timelines. I am ready to start immediately after agreement!
